Brighten. Protect. Radiate.

Vitamin C, reimagined for sensitive skin. The NUMBUZIN No.5 Vitamin Concentrated Serum delivers a potent multi-vitamin brightening complex in a stable, non-irritating formula that works around the clock to fade dark spots, even skin tone, and flood the complexion with a luminous, healthy glow. Unlike traditional L-ascorbic acid serums that oxidise quickly and sting on application, this serum uses a stabilised vitamin complex that remains effective from the first drop to the last — making consistent daily use effortless and results genuinely visible.

How to Use

1. After cleansing and toning, dispense 2–3 drops onto clean fingertips.
2. Gently press and pat into face and neck until fully absorbed — do not rub.
3. Allow to absorb fully before applying moisturiser.
4. Use morning and/or evening.
5. In the morning, always follow with SPF 30+ — vitamin C increases photosensitivity and SPF amplifies its brightening results.

Tip: Apply in the morning before SPF for maximum antioxidant protection against UV-induced pigmentation — vitamin C and SPF work synergistically to prevent new dark spots from forming while fading existing ones. Layer under the NUMBUZIN No.5+ Dark Spot Laser Cream for a complete brightening routine.

Key Ingredients

• Stabilised Vitamin C Complex — A multi-form vitamin C blend that delivers the brightening and antioxidant benefits of ascorbic acid without the instability or irritation — inhibiting tyrosinase to fade dark spots, stimulating collagen synthesis, and protecting against free radical damage for a visibly more even, radiant complexion.
• Niacinamide — Blocks the transfer of melanin to skin cells to brighten dark spots and even skin tone, while minimising pores and strengthening the skin barrier — amplifying the overall brightening effect of the vitamin complex.
• Vitamin E (Tocopheryl Acetate) — Works synergistically with Vitamin C to enhance antioxidant protection, stabilise the formula, and deeply nourish the skin barrier for a soft, comfortable finish.
• Adenosine — A clinically recognised anti-ageing active that smooths fine lines and supports skin elasticity, adding a firming dimension to the brightening serum.
• Sodium Hyaluronate — Delivers deep, lasting hydration to keep skin plump and comfortable, ensuring the vitamin actives absorb without any dryness or tightness.
